Filter Nipple 13/16-16

The Filter Nipple 13/16-16 by DERALE is a precision-engineered coolant adapter designed for integrated cooling system modifications and custom fluid management in modern automotive builds. This fitting serves as a critical junction point in bypass or auxiliary cooling circuits, allowing you to redirect coolant flow to aftermarket coolers, heater cores, or filtered reservoirs without compromising factory hose routing integrity.

The 13/16-16 designation identifies the barbed nipple inlet (13/16 inch) paired with a 16 TPI threaded port connection, enabling dual-media compatibility in cooling or fluid transfer applications. DERALE's manufacturing precision ensures concentricity and burr-free edges that eliminate leaks at the barb-to-hose interface while the threaded outlet accepts standard fittings or block adapters. Compact dimensions—measuring 2.75 by 1.4 by 4.15 inches—allow this fitting to nestle into tight engine bay spaces without requiring costly custom bracket fabrication.

Professionals and enthusiasts alike will benefit from this adapter when building high-performance street machines or upgrading track-dedicated vehicles. Its design facilitates the installation of auxiliary transmission or engine oil cooling systems, ensuring a clean, leak-free interface. The lightweight construction resists corrosion in glycol-based coolant environments and maintains structural integrity under the pressure demands of mechanical water pumps or auxiliary cooling loops.
